network arp

Use this command to add or delete an address resolution protocol (ARP) table entry, or to display the ARP table. The ARP table is used to resolve the IP addresses that correspond to a network interface card’s physical MAC address, thereby determining which IP addresses can be reached directly through a link.

To use this command, your administrator account’s access control profile must have rw or w permission to the sysgrp area. For details, see "Permissions" on page 1.

Syntax

diagnose network arp add <interface_name> {<interface_ipv4> | interface_ipv6>} <mac-address_hex>

diagnose network arp delete <interface_name> {<interface_ipv4> | interface_ipv6>}

diagnose network arp list
